摘    要:采用POM模式研究了南海对于台风伊布都的响应过程.结果表明:台风过后,海洋表面温度下降2—6℃,且在台风路径两侧不对称,具有明显的右偏性.受台风强混合作用的影响,混合层加深10—60m,上混合层热量损失约824.78W/m2,其中垂向混合是造成热量损失的主导动力因素.由于受上混合层热通量输送的影响,混合层以下附近水层处于增温状态,海水温度做近惯性波动.同时,台风还能引起强烈的近惯性流,最大流速出现在上混合层,可达1.4m/s. 关键词: 南海 台风 上层海洋 近惯性波动

关 键 词:南海  台风  上层海洋  近惯性波动

Abstract:The response of the South China Sea (SCS) to Typhoon Imbudo was examined using POM model. The results indicated that SST decreased by 2—6℃with a rightward-biased response as Typhoon Imbudo passed across the SCS. Due to a strong mixing process, the mixed layer (ML) depth deepened as much as 10—60m and ML heat budget lost 824.78W/m2, which was dominated by the vertical mixing. By the response of upper ML heat transport, the temperature below the ML increased and oscillated near the inertial period. Furthermore, strong inertial currents were generated by the storm with the max currents up to 1.4m/s in the upper ML.
Keywords:SCS  typhoon  upper ocean  inertial oscillation
